A wireless access network device manages data transmission to an end device over an unlicensed radio spectrum downlink channel. The device stores a threshold power value and monitors the downlink channel for data to transmit. When data is ready, the device measures the current power level on the downlink channel and compares it to the stored threshold. If the measured power meets or exceeds the threshold, the data is transmitted. The device then evaluates the transmission success or failure based on feedback from the end device. If the transmission fails, the threshold power value is increased to reduce interference risk in subsequent attempts. If the transmission succeeds, the threshold is decreased to improve efficiency. This adaptive approach dynamically adjusts the power threshold based on real-time conditions, balancing reliability and spectrum utilization in unlicensed bands. The method ensures efficient use of unlicensed spectrum while maintaining communication quality.
